What Superior Gearbox does
Superior Gearbox Company, founded in 1975 and headquartered at 803 West Street, Stockton, Missouri, is a privately held US manufacturer of mechanical power transmission components. The company designs and produces bevel gear drives, worm gear reducers, helical gearmotors, spindle drives, and fully custom gearbox assemblies. Manufacturing is anchored in a 44,000 sq ft Stockton facility housing engineering, machining, and corporate operations and a 77,000 sq ft Buffalo, Missouri facility dedicated to assembly, with a third operational site in Waterville, Minnesota, yielding a combined footprint of 121,000+ sq ft across Missouri and Minnesota. The product catalog spans standardized R-series and W/I-series bevel and worm drives, the Variodrive and CleanDrive industrial worm gear reducer platforms, the SGR/SGK/SGF/SGS helical gearmotor family, and bespoke gearbox solutions built from concept through prototyping and testing entirely in-house.
The business model is OEM-direct, enterprise, and quote-based. Superior Gearbox sells primarily to equipment manufacturers in agriculture, material handling, mining, construction, and food and beverage processing under custom pricing with multi-year program orientations; no public price list is published, and quotes flow through phone (1-800-346-5745), email ([email protected]), and an online RFQ portal. A dedicated aftermarket storefront, Superior Gearbox Direct, monetizes replacement parts, seals, bearings, and repair kits outside the OEM channel. The go-to-market relies on direct field sales supported by participation in industry trade shows (Equip Expo, World Ag Expo, AGRITECHNICA, World of Concrete, FEMA, AEM), domestic-manufacturing positioning as a tariff and lead-time hedge against imports, and custom engineering services that take customer-specified torque, ratio, mounting, and environmental requirements through prototyping and testing. Revenue is concentrated in custom hardware sales, with aftermarket parts and engineering services as supplementary streams; the company reports no external funding, no parent entity, and no public listing.
